Application filed April 19, 1909. Serial No. 490,739. I p 4 To all whom it concern:

Be it known that I, 'Ronnnr GEORGE MARSH, a citizen of the United States of America,- residing at d)etroit,.in the county of V ayne-and State of Michi an, have invented certain new and use ul Improvements in Dispensing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawm s.

This invention relates to dispensing apparatus, suitable for soda water fountains or the like, and more especially to an arrangement thereof whereby a movement in one direction of a single member causes a discharge of a measured quantity of syrup or other uncharged liquid together with a definite quantity of charged, carbonated or aerated water or the like under pressure,

the flow of the latter being restricted or otherwise changed at the end to agitate the v in the lower end of discharged liquid into foam, as in the customary way. The device is also self-registering or adapted to record the number of drinks. sold.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view in vertical section of one unit of a portion of a dispensing apparatus embodying features tion at right angles to Fig. l, of a measurmg chamber, barrel and' operating parts. Fig. 3 is a view of a chamber, bonnet and adjacent parts. Fig. 4 is a plan view of a chamber and bonnet. Figs. 5 and 6 are views in detail of a controlling valve closure. A series of syrup tanks or receptacles 1 are secured beneath the top of a tablefor counter, preferably by ledges 2 on their open, upper ends sliding on the lower flanges 3 of parallel I-beams .4. A hollow cover or measuring chamber 5 rests either on the to of each tank directly, or, as. herein indicate is supported on the upper flanges 6 of the I- beams whereby they may be drawn out if or they may be arranged in other by a ferrule 10 screw-threaded on the depending end of the boss. The latter is axif tends throng suitable inlet valve standard rod i nected with the bore of the rod by a duct 23 of the invention, together with parts of ada spindle 2 aperture'd and a tubular piston rod 11 1s longitudinally reciprocable therein. An upwardly opening check valve 12 is placed the piston rod, and a piston head or plunger 13 of any preferred construction is secured thereon, and has a slidmg fit in a short barrel 14 which forms a measuring vessel for the -syrup or non-carbonated l1quid.. The barrel is suitably supported from the cover near the bottom of the tank l, as by stirruplarms 15 whose upper convergent ends are secured to or formed integrally on the ferrule 10, which may likewise constitute-a stufiing box to retain packing 16 around the iston rod. An inwardly opening check val i e 17 of any preferred inlet in the lower part ally form issecured in an of the barrel 14 or the piston itself may uncover properly disposed inlet ports or other construction used in pump design, may be employed. The upper ortion of the piston rod 11 exthe cover 5 into a hollow valve casing or bonnet 18, preferably integral with the cover, in the form of a horizontal cylinder with end piecesl9 and 20, screw-threaded or otherwise detachably secured thereon.

A cap 21 on the upper end of the piston 11 has a lateral nipple 22 that is conand extends into theupper end of a mouth piece or nozzle 24 on the side of the bonnet 18. Rack teeth 25 on an extension of the cap are engaged by a segmental gear 26 on one end 28 of which engages a bearing'in awall 29 of the bonnet while the other extends through the end piece 20, a collar 30 and interposed friction bearing .31 of any preferred type forming an end thrust bearing.

A valve closure 32 is seated in a counterbored recess in the outer face of the wall 29 in axial alinement with the spindle 27, with an axial stem 33 extending through and journaled in the end piece 19. The closure is turned in unison with the spindle 27 by a yoke 34 of-ap ropriate design spanning the bonnet 18 an terminating in an operating handle 35. The closure. 32 is ported to connect an axial opening in the recess or seat, which is the mouth of a passage 50in the cross-wall 29 whose lower end opens into the interior or the cover 5 near the bottom plate 9, with a duct 51 extending through the wall 29 and a boss 52 to the exterior face of the nozzle through thellarge short pipe, thus flange, when the handle 35 is at the rearward. part of its throw, with the piston 13 raised to the upper end of the barrel 14. Theboss 52 is mteriorly screw-threaded or otherwise fitted for pipe connection with a charging tank.

When the handle is approaching its forward limit of motion, the closure 32 is ada ted to-connect the passage 50 with a disc arge opening 36 through the wall 29 which leads to a short pipe 37 delivering into the upper end ofthe nozzle 24. As the handle reaches its forward limit, the disk 32 connects the passage 50 with a smaller restricted duct 38from the outer end of which a tube 39, smaller than the pipe 37, leads to the mouth of the nozzle 24.

As a preferred form of construction, the closure 32 is a disk with a transverse channel 40, and a acking 41 of suitable material on its face. transverse rib 42 on the outer face of the disk engages a diametrical slot in the adjacent enlarged end or collar of its stem 33 so as to turn therewith. A take-up screw 43 in an axial aperture of the stem bears against the rib, and is set up as the valve wears, to prevent the leakage. A cap 44 onthe outer end of the stem, which is keyedv or otherwise non-rotatably locked with theyoke 34, covers the stem end. A friction bearing 45 of any a proved form between the stem collar an bonnet end piece 19 is provided to resist end thrust. The segmental gear 26 has an arm 46 with stud 47 engaging a lever, armor other member 48 or is otherwise operatively connected to a registering device 49 of any conventionaltype which is mounted in the barrel 18 with its face, .dial, or register plate visible throu h a view-hole in the. bonnet, so that a stro e of the operating handle-is registered on the dial.

, In operation, the handle, when moved to its normal, rearward position, draws the piston to the top of the measuring barrel, filling it from the contents of the receptacle or jar. At the same time, it turns the valve closure so that the-top ormeasuring chamber is connected with the char ing tank and is at once filled therefrom. hen the oper- 'ator wishesto draw a glass','he rocks the handle forward, thereby depressing the piston and forcing a definite amount of syrup up through the piston rod and its cap into the nozzle which empties into the glass. As the handle moves forward, it opens the charged top or measuring chamber into the drawing 'a comparative y quiet stream of the carbonated water into the glass. It then shifts this discharge into the small pipe which ejects a small stream with sufiicient force into the glass to produce the usual foaming effect desired. A reversal of the handle restores the parts to the initial position. Each forward movement of the lever is likewise recorded on the registering mechanism. 1

Obviously, changes in the details of construction may be -made without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.
